A prolonged mid summer heat wave continues through Saturday, with an oppressive area of high pressure from the mid Atlantic to the Ohio Valley is expected to remain nearly stationary through Friday.

This will result in a continuation of very hot and humid conditions, with a heat advisory in effect from 11 a.m. to 8 p.m. Friday.

Temperatures will be in the low 90s, with heat index values around 100 except in the higher elevations.

The highest heat will be between 1 and 6 p.m. Friday.

The heat will create dangerous conditions, especially for those working in the sun or living in non air conditioned homes.

The most adversely affected are young children and adults over 50. Leaving anyone, including pets and children, in non air conditioned cars during the day is very dangerous and quickly can become fatal.
